Some 1800 years ago Roman soldiers effectively used slings as deadly weapons. The length of these slings averaged about 81 cm and the lead shot that they used weighed about 30 grams. If in the wind up to a release, the shot rotated around the Roman slinger with a period of .14 seconds.
Find the maximum acceleration of the shot before being released in m/s^2 and report it to two significant figures.
